Alec Robertson, MBE (3 June 1892, Southsea – 18 January 1982, Midhurst) was a British writer, broadcaster and music critic. He wrote music criticism for Gramophone for more than 50 years, beginning with the magazine's very first issue in 1923. He later served as that magazine's music editor from 1952–1972.
In 1950, Robertson succeeded Ralph Hill as editor of Music magazine, on the latter's death, having previously written a record review column for its predecessor, Penguin Music Magazine. He also wrote for The Catholic Herald, and The Tablet.
He appeared as a "castaway" on the BBC Radio programme Desert Island Discs on 3 June 1957, and again on 3 June 1972.
Robertson was educated at Bradfield College and the Royal Academy of Music. He was named a fellow of the latter institution in 1946. In 1972, he was made a Member of the Order of the British Empire.
